This update for shim fixes the following issues:

Support a nx-shim (jsc#PED-13361 jsc#PED-15978):

This marks data sections as 'non executable' during the UEFI boot process.

shim-install: separate the logic of grabbing OS_ID
When the GRUB_DISTRIBUTOR can be grab by /etc/default/grub. The
logic of grabbing OS_ID from os-release will be ignored.
For example: SL-Micro 6.1 has GRUB_DISTRIBUTOR='SL Micro' in
/etc/default/grub.

We always need OS_ID for subsequent processing logic. So this
patch separate the logic of grabbing OS_ID. (bsc#1285863#c14)

shim-install: refactory the logic of update_boot for fixing two issues
Refactory the logic of update_boot for updating EFI default boot path
in shim-install and fixed two issues:

- The fallback efi NOT be copied to the default efi boot path for SLE
  (bsc#1285863)
- The encrypted SL-Micro uses 'removable=yes' for TPM key unsealing. But
  the original logic did NOT copy MokManager to EFI default boot path.
  (bsc#1285863#11)


- Add Requires tags for checking the grub2 sbat generation at RPM
  level, so we make sure we are not blocking the grub2 during boot. (bsc#1278729)


- Use nx shim as the default shim binary for SLES 16.1 and newer
  in older versions the non-nx shim is default. The nx shim
  can still be selected.

- shim-install: Do not update fallback on sl-micro when the fallback
  is not in efi default boot path

  The SL-Micro SelfInstall image direct unpackage the raw image to
  the hard drive on target machine. The kiwi produced the raw image
  by 'shim-install --removable' command. So the raw image does NOT
  include fallback.efi in the EFI default boot path (aka. the
  removable boot path, EFI/boot/). Looks that SL-Micro does NOT care
  the fallback function of SUSE boot entry is lost.
  Normally, with or without fallback.efi should NOT case problem when
  booting. Also, the distro (SL-Micro in this case) does NOT care fallback
  function. But some issue machine's firmware can ONLY boot with the
  removable boot path (aka. the default boot path, /EFI/boot/bootx64.efi).
  And issue firmware always modified boot order or even removed SUSE boot
  entry. It causes that the fallback.efi always be triggered in every
  booting. The outward symptom is an endless cycle of rebooting and showing
  the fallback prompt box.
  The above situation NOT be found before we fix bsc#1254336. In
  bsc#1254336, the shim-install did NOT update the files in removable boot
  path. e.g. /EFI/boot/bootx64.efi or /EFI/boot/fallback.efi.
  So we will NOT update fallback.efi on SL-Micro when shim-install did NOT
  see fallback in the removable boot path (EFI/boot/fallback.efi). No
  fallback.efi in the removable boot path means that the target system
  is installed by wiki raw image.  (bsc#1270036)

- Update shim-install to limit the scope of the 'removable' SL-Micro to the image booting with TPM2 unsealing (bsc#1210382)
- shim-install: Add ca_string for SL Micro to update fallback loader (bsc#1254336)
- Update change log for shim-install add ca_string for SL Micro to update fallback loader (bsc#1254336)
- Modified the pretrans Lua script to work around the broken DB issue caused by buggy firmware when Secure Boot is disabled.  (bsc#1259096)
- shim-install: Improve the detection of SL Micro (bsc#1269084)


The following package changes have been done:

- shim-16.1-150300.4.42.1 updated
